Lang Martin de25fc6cf4 csi: csi-hostpath plugin unimplemented error on controller publish (#7299)
* client/allocrunner/csi_hook: tag errors

* nomad/client_csi_endpoint: tag errors

* nomad/client_rpc: remove an unnecessary error tag

* nomad/state/state_store: ControllerRequired fix intent

We use ControllerRequired to indicate that a volume should use the
publish/unpublish workflow, rather than that it has a controller. We
need to check both RequiresControllerPlugin and SupportsAttachDetach
from the fingerprint to check that.

* nomad/csi_endpoint: tag errors

* nomad/csi_endpoint_test: longer error messages, mock fingerprints

Tim Gross b04d23dae0 csi: ensure volume query is idempotent (#7303)
We denormalize the `CSIVolume` struct when we query it from the state
store by getting the plugin and its health. But unless we copy the
volume, this denormalization gets synced back to the state store
without passing through the fsm (which is invalid).

Tim Gross de4ad6ca38 csi: add Provider field to CSI CLIs and APIs (#7285)
Derive a provider name and version for plugins (and the volumes that
use them) from the CSI identity API `GetPluginInfo`. Expose the vendor
name as `Provider` in the API and CLI commands.

Lang Martin a4784ef258 csi add allocation context to fingerprinting results (#7133)
* structs: CSIInfo include AllocID, CSIPlugins no Jobs

* state_store: eliminate plugin Jobs, delete an empty plugin

* nomad/structs/csi: detect empty plugins correctly

* client/pluginmanager/csimanager/instance: allocID

* client/pluginmanager/csimanager/fingerprint: set AllocID

* client/node_updater: split controller and node plugins

* api/csi: remove Jobs

The CSI Plugin API will map plugins to allocations, which allows
plugins to be defined by jobs in many configurations. In particular,
multiple plugins can be defined in the same job, and multiple jobs can
be used to define a single plugin.

Because we now map the allocation context directly from the node, it's
no longer necessary to track the jobs associated with a plugin
directly.

* nomad/csi_endpoint_test: CreateTestPlugin & register via fingerprint

* client/dynamicplugins: lift AllocID into the struct from Options

* api/csi_test: remove Jobs test

* nomad/structs/csi: CSIPlugins has an array of allocs

* nomad/state/state_store: implement CSIPluginDenormalize

* nomad/state/state_store: CSIPluginDenormalize npe on missing alloc

* nomad/csi_endpoint_test: defer deleteNodes for clarity

Tim Gross 8bc5641438 csi: volume claim garbage collection (#7125)
When an alloc is marked terminal (and after node unstage/unpublish
have been called), the client syncs the terminal alloc state with the
server via `Node.UpdateAlloc RPC`.

For each job that has a terminal alloc, the `Node.UpdateAlloc` RPC
handler at the server will emit an eval for a new core job to garbage
collect CSI volume claims. When this eval is handled on the core
scheduler, it will call a `volumeReap` method to release the claims
for all terminal allocs on the job.

The volume reap will issue a `ControllerUnpublishVolume` RPC for any
node that has no alloc claiming the volume. Once this returns (or
is skipped), the volume reap will send a new `CSIVolume.Claim` RPC
that releases the volume claim for that allocation in the state store,
making it available for scheduling again.

This same `volumeReap` method will be called from the core job GC,
which gives us a second chance to reclaim volumes during GC if there
were controller RPC failures.

Seth Hoenig 9df33f622f nomad: proxy requests for Service Identity tokens between Clients and Consul
Nomad jobs may be configured with a TaskGroup which contains a Service
definition that is Consul Connect enabled. These service definitions end
up establishing a Consul Connect Proxy Task (e.g. envoy, by default). In
the case where Consul ACLs are enabled, a Service Identity token is required
for these tasks to run & connect, etc. This changeset enables the Nomad Server
to recieve RPC requests for the derivation of SI tokens on behalf of instances
of Consul Connect using Tasks. Those tokens are then relayed back to the
requesting Client, which then injects the tokens in the secrets directory of
the Task.

Seth Hoenig 2b66ce93bb nomad: ensure a unique ClusterID exists when leader (gh-6702)
Enable any Server to lookup the unique ClusterID. If one has not been

apply it through raft.

The value is not yet used anywhere in this changeset, but is a prerequisite
for gh-6701.

Seth Hoenig d45dec1ca8 tests: parallelize state store tests
It has been decided we're going to live in a many core world.
Let's take advantage of that and parallelize these state store
tests which all run in memory and are largely CPU bound.

An unscientific benchmark demonstrating the improvement:

[mp state (master)] $ go test
PASS
ok  	github.com/hashicorp/nomad/nomad/state	5.162s

[mp state (f-parallelize-state-store-tests)] $ go test

Mahmood Ali 02e20c720b acl_endpoint: permission denied for unauthenticated requests
If ACL Request is unauthenticated, we should honor the anonymous token.
This PR makes few changes:

* `GetPolicy` endpoints may return policy if anonymous policy allows it,
or return permission denied otherwise.
* `ListPolicies` returns an empty policy list, or one with anonymous
policy if one exists.

Without this PR, the we return an incomprehensible error.

Before:
```
$ curl http://localhost:4646/v1/acl/policy/doesntexist; echo
acl token lookup failed: index error: UUID must be 36 characters
$ curl http://localhost:4646/v1/acl/policies; echo

Michael Schurter e4bc943a68 nomad: SnapshotAfter -> SnapshotMinIndex
Rename SnapshotAfter to SnapshotMinIndex. The old name was not
technically accurate. SnapshotAtOrAfter is more accurate, but wordy and
still lacks context about what precisely it is at or after (the index).

SnapshotMinIndex was chosen as it describes the action (snapshot), a
constraint (minimum), and the object of the constraint (index).
